Connecting the Power supply

Use an optional PS-126
operating the IC-78 with AC power. Refer to the dia-
grams below.
CONNECTING THE PS-126 DC POWER SUPPLY
CONNECTING A NON-ICOM DC POWER SUPPLY
CONNECTING A VEHICLE BATTERY
• RWARNING! NEVER connect to a battery
without using a DC fuse, otherwise a fire hazard
could occur or damage to the transceiver.
• NEVER connect the transceiver to a 24 V battery.
The transceiver may not receive well on some
frequencies when installed in a hybrid vehicle, or
any type of electric vehicle (fuel cell vehicle). This is
because vehicle's electric components, such as the
inverter system, generate a lot of electric noise.

• DO NOT use a cigarette lighter socket as a power
source when operating in a vehicle. The plug may
cause voltage drops and ignition noise may be
superimposed onto transmit or receive audio.
• Use a rubber grommet when passing the DC
power cable through a metal plate to prevent a
short circuit.
